Dewar9 suggests older people may be reluctant to report pain and have a stoic approach, accepting incorrectly that pain is part of the normal aging process. Pain is not a normal part of ageing, but its prevalence increases with age and illness, reaching its highest levels among older people in residential care settings.10 For persistent pain which is resistant to common therapies, Older people may be medications or alternative methods, the health care professional should consider referral to specialist pain clinics.10 In 2005, Schofield et al.11 suggested the need for chronic pain reluctant to report services in the community; in the current climate, this is more evident than ever. In jurisdictions that are moving forward with pain and have a stoic a national strategy for pain (such as Australia), this is already happening; specialist pain teams are moving into the heart of the issue in primary care.12 approach, accepting Assessment of pain incorrectly that pain A patient’s own report is the most reliable indicator of their pain and when possible this should be obtained.4 A self-report of pain is also possible in those with mild to is part of the normal moderate cognitive impairment with standard assessment tools or if required with more specialised tools such as the Iowa Pain aging process.
